Efectos adversos en cirugia general. Analisis prospectivo de 13.950 pacientes consecutivos

INTRODUCTION Adverse event (AE) rates in General Surgery vary, according to different authors and recording methods, between 2% and 30%. Six years ago we designed a prospective AE recording system to change patient safety culture in our Department. We present the results of this work after a 6 year follow-up. MATERIAL AND METHOD The AE, sequelae and health care errors in a University Hospital surgery department were recorded. An analysis of each incident recorded was performed by a reviewer. The data was entered into data base for rapid access and consultation. The results were routinely presented in Departmental morbidity-mortality sessions. RESULTS A total of 13,950 patients had suffered 11,254 AE, which affected 5142 of them (36.9% of admissions). A total of 920 patients were subjected to at least one health care error (6.6% of admissions). This meant that 6.6% of our patients suffered an avoidable AE. The overall mortality at 5 years in our department was 2.72% (380 deaths). An adverse event was implicated in the death of the patient in 180 cases (1.29% of admissions). In 49 cases (0.35% of admissions), mortality could be attributed to an avoidable AE. After 6 years there tends to be an increasingly lower incidence of errors. CONCLUSIONS The exhaustive and prospective recording of AE leads to changes in patient safety culture in a Surgery Department and helps decrease the incidence of health care errors.

Learning curve for d2 lymphadenectomy in gastric cancer.

Background. D2 lymphadenectomy is a demanding technique which is associated with high morbidity in the West. We report our experience with D2 lymphadenectomy after a training period in Japan. Methods. Prospective, descriptive study in 133 consecutive patients undergoing radical gastrectomy for gastric adenocarcinoma from 2005 to 2011. We analysed the number of lymph nodes removed, observed morbidity/mortality compared with the predictions of POSSUM and O-POSSUM, survival, and disease-free interval for patients with D1 and D2 lymphadenectomy. Results. The morbidity rate in patients with D1 lymphadenectomy was 59.4%. For D2 it was 47.7%. The mortality rate in patients with D1 was 6.7%. In the D2 group it was 6.8%. Median survival was 42.9 months in D1 and 55 months in D2. The disease-free interval was 49 months for D1 and 58 months for D2. Conclusion. The learning curve for D2 lymphadenectomy presents acceptable rates of morbidity and mortality, providing that the technique is learnt at a center with extensive experience.

Origen de la hemorragia en pacientes politraumatizados con fractura de pelvis e inestabilidad hemodinámica

INTRODUCTION The main cause of mortality in trauma patients with pelvic fractures is hypovolemic shock. We analyzed the association between the source of bleeding, mechanism of action and type of fracture. METHODS Prospective descriptive study involving trauma patients older than 16 years old, admitted to the intensive care unit or dead before admission, with pelvic fractures and hemodynamic instability. Hemodynamic instability was defined as SBP <90 and/or HR> 100 beats/min. Pelvic fracture was defined by the Tile classification. RESULTS A total of 157 of 1088 trauma patients had pelvic fracture. We included 63 patients, all hemodynamically unstable. A total of 85% of pelvic fractures after falls from great heights bled from the fracture itself, compared to only 44% of victims of impact (hit). A total of 65% of patients with stable pelvic fracture bled from associated lesions; 70% of patients with unstable fracture bled from the fracture itself. There is an interaction between the mechanism of action and type of fracture. The probability of pelvic bleeding is higher in the precipitated patient (> 80%) regardless of the type of fracture. Bleeding from associated injuries is greater in impact victims, doubling when the fracture is stable (91%). CONCLUSIONS Mechanism of action is a key to determine the source of bleeding in patients with pelvic fracture. After falls patients bleed from the fracture itself, while patients with an impact (hit) can bleed both from the fracture and associated injuries, depending on the type of fracture.
